SILENCER FOR FLUSHING-TANKS.

Specification of Letters Patent.

Patented July 31, 1917.

Application filed. August 25, 1913. Serial No. 786,452.

To all whom it may concern:

Be it known that I MARY'V. Gnoss, a citizen of the United tates, residing at Los Angeles, in the county of Los Angeles and State of useful Improvements in a Silencer for Flushing-Tanks, of which the following is a specification. I

This invention relates to a silencer for flushing tanks and it has for its object to provide an improved flushing tank in which I the disagreeable noises usually attendant upon the discharge and refilling of flushing tanks willbe eliminated.

In the drawing Figure l is a vertical transverse sectional view of a flushing tank organized in accordance with the invention, parts being broken away for olearness of illustration.

Fig. 2 is a reduced sectional view taken on line w m Fig. 1 and looking in the direction of the appended arrows.

Corresponding parts in all the figures are designated by the same reference characters.

Referring with particularity to the drawing, the improved flushing tank therein shown comprises a battle member A, a tank or reservoir B and inlet valve means and discharge valve means C and D, respectively. Coming down to the particular construction and organization of the improved flushing tank, the baffle member A comprises a tubular body 4 provided with a reducing bushing 5 into which is threaded a water supply pipe 6 leading from any suitable v source of Water supply. Into a similar reducing bushing 7 provided .at the outlet end 4 of the tubular body 4 is threaded a pipe connection 8 which is connected as at 9 to the inlet pipe 10 leading to the tank B.

Within-the tubular body 4 and at a short distance from the reducing bushing 5 is arranged a series of alternately placed transverse bafiie partitions 11 and 12, the partitions 11 being each provided with a plu- 'rality of parallel slots 11 and the partitions 12 being each provided with a plurality of similar parallel slots 12, the slots 12 provided in the partitions 12 being arranged at an angle of ninety degrees to the slots 11 provi ed in the partitions 11. The partitions 11 and 12 are spaced apart to provide a series of water spaces or chambers 13.

A reducing nozzle 14 which is preferably of funnel form is secured to the tubular California, have invented new and body 4 and arranged with its nozzle 15 extended into a parabolic'reflector 16 which is secured to the tubular body 4 and'held centrally therein by the arms 17.

The tank B preferably comprises an inner lining having downwardly and inwardly inclined side walls 18 and 19, end walls 20 and 21 and a relatively narrow bottom 22, such lining being disposed in a suitable outer supporting casing 23.

Within the tank B are mounted the inlet valve means C and the discharge valve means D.

The inlet valve means C may comprise an operating arm'24 upon which is mounted a valve 25 which coacts with a valve seat 26 provided at the terminus 27 of the inlet pipe 10, the operating arm being pivoted as at 28 and provided with a float 29 at its free end, or the inlet valve means may be a device of any preferred form, the only requirement being that it be so organized as to positively control the supply of water to the tank, so that water may rise in the tank to a predetermined level and no higher. The

inlet pipe 10 preferably enters the lining of the tank at or near one end as at 30.

The discharge valve means D comprises a slide valve 31 applied to the wall 18 of the liner, a discharge orifice 32 in the liner, which is normally closed by the valve, and a valve operating rod 33 one end of which is secured to the slide valve as at 34 and the other end of which is connected to a manually operable lever or the like 35 by means of a suitable connection 36. Mounted upon the rod 33 is a piston 37 which has a sliding fit in a cylinder 38 which acts as a dash pot to retard the valve in its descent after it has been raised to allow the contents of the tank to escape. A suitable connection 39 is secured to the liner of the tank outward of the discharge orifice 32, connecting the tank with the flushing pipe or conduit 40.

The operation of the improved flushing tank is as follows: Water from a suitable pressure supply or head, supplied through the pipe 6 enters the baifle member A above the series of bai'lle partitions 11 and 12 its momentum being partially checked by the first of the baiile partitions 11 which it encounters, as well as by reason of its enter ing the tubular member 4 which is of considerably greater transverse area than the pipe 6. When the momentum of the water has thus been partially checked it is ad- 'which it is allowed to pass into the next chamber 13 of the series through the slots 12 in the first 0f the baflle partitions 12 in the series of partitions, and so on, progressively through the entire series, the cross- 7 wise placing of the slots 11 and 12 com pelling the water to take a tortuous course, each succeeding partition serving to further reduce'its momentum. When the entering water has passed the entire length of the series of baflle partitions 11 and ,12 it enters the reducing nozzle 14: and passes there through, impinging upon the parabolic reflector 16 and being thereby reversed in direction of flow, and again reversed as it escapes over the edge of the reflector after which it is permitted to pass out of the tubular body 4, through the connection 8 and the inlet pipe 10 into the tank, subject to the control of the inlet means C, such means allowing water to enter until the float 29 is raised sufliciently by the water in the tank to cause the lever arm 24: to press the valve 25 against the valve seat 26 thereby shutting off any further inflow of water. This operv ation is without the objectionable noise usually attending the filling of flushing tanks. When the manually operable-lever is manipulated to raise the slide valve 31 the water in the tank is allowed to escape through the orifice 32 and through the con- As the water level in the tank falls, the

float 29 descends and causes the lifting of the valve 25 from its seat thus permitting the automatic refilling of the tank.

Having thus described my invention, I desire to secure by Letters Patent A silencer for flushing tanks, comprising a tubular member of enlarged diameter with respect to its inlet and outlet, a plurality of spaced perforated baflle plates disposed in said tubular member transverse to the axis thereof, a reflector in said tubular member, a reducing nozzle in said member between said baflle plates and reflector, said bafile plates each having a plurality of elongated apertures, the planes of the apertures .of adjacent plates intersecting.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
